Frontend State Management Planner
Example session with this skill installed
Plan the state for a multi-step checkout flow. Users select products, enter shipping, and pay. We need to handle validation, address autocomplete, and preserve progress if they refresh.
- Read your context and instructions
- Compiled the frontend state management
I have analyzed the checkout flow requirements. The plan prioritizes local form state for performance while using persistent storage for progress recovery.
Checkout Flow State Management Plan
State Inventory
| State/Data | Classification | Source of Truth | Owner | Consumers | Persistence | Update Path | Reason |
|---|---|---|---|---|---|---|---|
| Cart Items | Global | API/Server | Cart Provider | Summary, Steps | LocalStorage | updateCart | Shared across all steps. |
| Current Step | URL/Router | URL Params | Router | Checkout Layout | None | router.push | Enables back/forward navigation. |
| Shipping Form | Form State | Component State | ShippingForm | Autocomplete | SessionStorage | onInputChange | High frequency updates; local scope. |
| Validation Errors | Derived | Form State | ShippingForm | Error Labels | None | Computed | Should not be stored separately. |
| Payment Intent | Server | Stripe/API | Payment Module | Payment Step | DB | createIntent | Security and transaction integrity. |
Data Flow
SELECT ADDRESS → AUTOCOMPLETE API → UPDATE FORM STATE → VALIDATE → SHOW SUCCESS
Architecture Recommendation
- Form Strategy: Use uncontrolled components with a validation schema (e.g., Zod) to minimize re-renders.
Persistence: Sync the Shipping Form state to SessionStorage on blur events to handle page refreshes without hitting the database.
*
Server Separation: Treat the Payment Intent as immutable server state. Do not mirror it into a global store; fetch it only when the Payment step mounts.
Implementation Checklist
- Step index is tracked in the URL for deep-linking.
- Shipping data is isolated from Payment data to prevent unnecessary re-renders.
- API errors include a retry trigger for the address lookup.
- Derived validation state is computed during the render phase.
Next steps
- Define the Zod schema for the Shipping Form based on these fields.
- Select a routing strategy (file-based or object-based) to handle the step transitions.
- Configure the SessionStorage sync hook for the form data.

About this skill
The problem
Developers often struggle with bloated global stores, prop drilling, and out-of-sync server data. Without a clear plan, state management becomes a tangled mess of duplicated sources of truth and unpredictable side effects.
What it does
- Analyzes product requirements to identify local, shared, global, and server-side state domains.
- Assigns explicit ownership and read/write scopes for every data item to prevent architectural drift.
- Maps complex data flows from user actions through handlers and APIs to UI updates.
- Flags risks like over-globalization, redundant derived state, and race conditions in async flows.
- Defines state transitions including loading, error, and optimistic update paths.
Frameworks & tools
Works with React, Next.js, Vue, Svelte, Angular, and React Native. Agnostic to state libraries but compatible with Redux, Zustand, TanStack Query, and XState.
Why this beats prompting it yourself
Generic prompts often default to suggesting Redux or global providers for everything. This skill applies strict ownership principles, forcing a "minimum viable scope" approach that separates server cache from ephemeral UI state, reducing technical debt from day one.
Use cases
- Architecting the data layer for a new feature or greenfield application.
- Refactoring a tangled "God Object" global store into manageable feature modules.
- Planning complex multi-step forms with cross-field validation and persistence.
- Designing robust synchronization between URL parameters and dashboard filters.
Known limitations
Does not generate implementation code or boilerplate. Focuses on architecture and planning logic rather than specific library syntax.
Architectural guidance only. Does not generate library-specific boilerplate or execute code. Framework-agnostic unless you specify your stack.
